I downloaded the Starkers nude theme recently and I have been redesigning my website with it. I was adding some functions to functions.php. and I noticed something: there is no closing tag at the end of the page for the PHP script. Is this an error OR does it not matter OR am I missing something? I don’t really know much about PHP, but this concerns me. Thank you in advance!
I’m pretty sure this isn’t an error. I’ve noticed it in the past and I’m fairly confident the functions file gets gets imported into the PHP of another file (or files) within WordPress. the closing tag is most likely included in that file. This allows WordPress to make sure key functions are always available. I’m not sure if that is actually happening but that’s what I’ve been lead to believe.

Not entirely true:
> If a file is pure PHP code, it is preferable to omit the PHP closing tag at the end of the file. This prevents accidental whitespace or new lines being added after the PHP closing tag, which may cause unwanted effects because PHP will start output buffering when there is no intention from the programmer to send any output at that point in the script.
Ben pretty much covered it. It’s just one of the quirks of PHP, though it definitely does seem odd after having HTML standards beaten into your head. I still find myself closing it out with ?> from time to time.
